WIRE FABRIC Filed May 16., 1930 Patented Nov. 24, 1931 EDWARD F. PINK, OF CAMBRIDGE, MARYLAND WIRE FABRIC 4Application led May 16,

' This invention relates to a wire fabric, the present invention being an improvement over lthat forming the subject matter of my Patent No. 1,735,788, dated November 12, 1929.

The general object of this invention is 'to produce a wire fabric of the maximum flexibility, of great tensile strength, and one in which the interstices are very small.

This invention also consists in certain other features of construction and in theV combination and arrangement of the several parts to be hereinafter fully described, illustrated in the accompanying drawings, and specifically pointed out in the appended claims.

In describing the invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which l Figure 1 is a view showing a portion of the fabric, this view being made on an enlarged scale to clearly shown the construction of the' fabric;

Figure 2 is a section von line 2-2 of Figure 1;

Figure 3 is a view showing a modification; and

Figure 4 is a section on line 4-4 of Figure 3. As shown in the drawings, the fabric is composed of a plurality of spiral coils of wires in which the wires are arranged in pairs, with the spirals of each pair passing through each other and lying in the same plane, with one s iral passing through the adjacent spirals o the next two pairs on the left of the rst pair, and the other spiral of the first pair passing through the adjacent spirals of the next two pairs on the right of the first pair. For instances, the spirals 1, 2 and 3 are woven together in the usual way and then the spiral 3 is moved to a position where it will bein alignment with the spiral 2. The spiral 4 is then woven into the spiral 3, with said spiral 4 in the same plane as the spiral 1. Then the spiral 5 is woven into the spiral 1 and a spiral 6 woven into the spiral 4, which places the spiral 6 in the same plane as the spiral 5. A spiral 7 is then woven int spiral5 and a spiral Sinto spiral 6. This 1930. .Serial No. 453,014.

places the spirals 7 and 8 in the same plane. This is continued until the fabric is of the desired length, or the ends of the fabric can be connected together to provide an endless belt. The ends of the spirals which overlap are soldered, Welded, or otherwise fastened together, as shown at 9.

Thus I'have produced a fabric of double strength, of the maximum iexibility, and one in which the interstices are twice as smallgas in the usual fabric, and this is accomplished by using as heavy a size wire as is ordinarily used in such fabrics. As shown, the fabric is a continuous woven one and not a fabric connected together by rods or staples, as in 65 the above-mentioned patent.

Figures 3 and 4 show rods 10 passing through the vertices of the spirals, which make the interstices smaller than ,when the rods are not used. vThe ends of the rods are 7o fastened to the overlapping ends of the spirals, as shown at 11.

It is thought from the foregoing description that the advantages and novel featuresI of the invention will be readily apparent.

It'is to be understood that changes may be j made in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claims. V

What I claim is 1. A wire fabric composed of spiral wires arranged in pairs, withothel spirals of each pair passing through each other and lying in the same plane, and a hingerod located 85 axially of the pair and engaging the adjacent coils of pairs on the right and left thereof.

2. A wire'fabric composed of wires arranged in pairs and each pair havingtheir ends rigidly connected and the spirals of each pair passing through each other and lying in the same plane, with one spiral of said first pair passing through adjacent spirals of pairs on the left of said lirst pair, the other spiral of the first pair passing through spirals of pairs on the right of the first pair, and a hinge rod located axially of each pair and having the ends thereof secured with the connected ends of each pair.

3. A wire fabric composed of wires arranged in pairs and each pair having their ends rigidly connected and the spirals of each pair passing through each other and lying in the same plane, rsb pair passing through ad'acent spirals of pairs on the left of said rst pair, the other spiral of the first pair passing through spirals of pairs on theI right of the rst palr;

a hinge rod located axially of the pair and engaging the adjacent coils of pairs on the right' and left thereof, each rod having its ends 'xed to the connected ends of the respec-A tive pairs.

In testimony whereof I afiixY my signature.

EDWARD F. PINK.
